Abstract

This paper presents the results of studies on the arc-proofness of insulating booms of aerial platforms for live line works. The data obtained with 5-20 kA power arcs applied for 1.5-0.1 sec, show acceptable arc-proofness of tested insulating boom samples and full-scale models as well as their ability to withstand nominal voltage or even switching overvoltages after such an arc, if autoreclosing occurs during live line work. The obtained results make possible further improvements of existing telescopic platforms.<>

110- 220kv火线工程成套工具的防弧性研究
本文介绍了火线工程架空平台绝缘吊臂防弧性能的研究结果。通过施加1.5-0.1秒的5-20 kA功率电弧获得的数据显示,所测试的绝缘臂样品和全尺寸模型具有可接受的防电弧性,并且能够承受标称电压,甚至在这种电弧后的开关过电压,如果在带电线路工作期间发生自动重合闸。所得结果为进一步改进现有伸缩平台提供了可能。
